My last blog post was something about the completion of the Trinity prototype. That was the first prototype, which was the most difficult part of the development stage. The next prototype I just completed which is a full on stereo version - v1 was mono to keep the development as simplified as possible. I finished v2 a couple days ago and that was no easy task, let me tell you. You'd think it would be easy to turn 1 channel into two, but I encountered power supply issues with things overheating and not enough heater current for 6 tubes, but that has been worked out. I also encountered cross-talk issues, which have also been worked out. Both issues were not easy to fix, but we're good now. Next is implementation of phantom power into the design. After that's 100% cool I'll move onto phase 3, the first production prototype. When the production prototype is complete Bryan Wray and I will be shooting a demo video of it before I ship the unit off to its permanent home at http://bambooroomstudio.com/.
On another note, I've been thinking about adding a new page to this website in which prototypes and used LBA gear will be offered for sale from time to time. The sale of such things will directly fund the development of new products. I'll put the completed Trinity on there, as well as a mono passive tube EQ prototype, which led to the development of the Flux Bender. There's also a used 5 watt guitar amp I made, which was the precursor to the Gravitone 30 and another passive eq prototype. Not sure how much to sell the prototypes for. Some like the "Teq1" passive EQ prototype I have a personal attachment to. That particular EQ is something I use fairly often at LBA Studios and it was the second piece of functional recording equipment I ever built (first was a passive summing box). Its really unique since it has in it not only my hand made capacitors, but also a multi-tapped inductor I wound by hand. Although I do have a personal attachment to this EQ, I would consider selling it for the right price. If it sells for a good price I won't feel terrible about letting it go and the money will help LBA move forward with new designs.
